Features:

  • Adds a maritime connection in Coupeville, WA
  • Integrates GUOA with the vanilla ATS road network
  • Rescales GUOA to 1:20 to match the ATS base map
  • Enables seamless travel between the USA and Grand Utopia of America
  • Fully compatible with the base ATS map
  • Compatible with the entire More American Cities mod series
  • Road signs in GUOA still display real 1:1 distances
  • Fixed support for the South Dakota DLC in this update
  • Compatibility with other third-party maps not guaranteed if they overlap
  • Tested on game version 1.61.x

This modification creates a direct maritime link between the base American Truck Simulator map and the Grand Utopia of America (GUOA) map, allowing drivers to travel naturally between the two worlds.

The connection is established at Coupeville, Washington, and adapts GUOA's scale to 1:20 so it matches the proportions of the vanilla map. Despite this scale change, the in-game road signs within GUOA continue to show the original 1:1 distances.

It's designed for players who enjoy the Grand Utopia of America map and want it to feel like a natural extension of the base game world, complete with compatibility for the More American Cities mod series.
